1 Claim. 1

This invention relates to a so-called hookover mounting for lenses for aiding the eyes.

In the mounting of lenses in a supplemental device of this character an attempt has been made to provide a combination hook for mounting the rims on a spectacle frame, and at the same time utilize the hook as a means for securing together the ends of each rim about its lens. In some cases the U-shape arrangement of the hook is made suficiently stiff so as to attempt to hold the rim by securing one leg on each end of the rim, but it is found that this is not sufficiently strong to hold the rim in closed position.

One of the objects of this invention is to modify the hook so that the hook may be utilized as a means for holding the ends of the rim together about the lens securely so that the same cannot spread to release the rims.

Another object of the invention is to provide a hook of a sufficiently ductile material so that the same may be easily bent one part about another to rely upon the wrapping action of the parts of the hook to hold same in position rather than the stiffness of the hook.

Another object of the invention is to fold one arm of the hook about another for securing this locked arrangement.

With these and other objects in view, the invention consists of certain novel features of construction as will be more fully described and particularly pointed out in the appended claim.

Figure 1 is a face View of a pair of rims for mounting lenses, with these lenses each equipped with the hook which is the subject of this invention;

Figure 2 is a fragmental perspective view illustrating the two hooks mounted on the rim with one of the hooks utilized for holding the ends of the rim in assembled relation;

Figure 3 is a fragmental perspective view of a portion of the rim showing the opening at the ends prior to the folding of one of the arms of the hook about the other to hold it in place;

Figure 4 is a perspective view showing the first step in the folding of the arm of one hook about the other arm; and

Figure 5 is an exploded view showing the hook and the rim before being joined together.

In proceeding with this invention I provide a hook in the form of a U-shaped member having a pair of arms with one arm attached to one end of a rim and the other arm attached to the other end of the rim. One of these arms is provided with a free end extending beyond the point of attachment to the rim so that by wrapping it about the other arm the arms are tightly held together.

' 2 With reference to the drawings, iiiifl designate rimsjoined together by a bridge portion H which is a resilient material, and attached as at 2 to each of the rims. Each rim it mounts a lens [3 within it by contracting the rim upon the lens. The rim has ends I l and it as shown in Figures 3 and 5 and the new hook which is utilized is designated generally it, having an arm i i which is soldered or welded to the end portion is of the rim and an arm 18 which is soldered or welded to the end portion I5 of the rim. The

bent portion iii of this U permits sufiicient bending or flexibility so that the ends at I 4 and 15 may be spread apart for the reception of the lens i3 within the rim. An extension 20 is provided on one of the arms such as l8 and is folded at an angle to the arm as at 22 away from its point of attachment to the rim l5. Thus, when the arms of the hook are attached to the ends of the rim they are in the position substantially as shown in Figure 3.

After the lens [3 is inserted in the rim and it is desired to close the ends of the rim and maintain the ends of the rim in position the ends of the rim are brought up snugly together and the extension 29 is folded back upon itself as shown in Figure 4 and then about arm I! and holds both arms bound together that the lens may be secured within the rim. The U-shaped member with its arms l'l' and is has both arms bent to provide right angular terminals for enaging spectacles for mounting the rims thereon.

I claim:

A lens mounting comprising a rim to encircle the lens with terminal end portions, a U-shaped member having a pair of arms with one arm secured to one end portion and the other arm secured to the other end portion, one of said arms having a free end extending beyond the point secured to the rim and being of suflicient length for wrapping about the other arm to bind the arms sufficiently close together to hold the lens in the rim.
